摘要

Treatment of a series of primary aliphatic and aromatic carboxamides ( - ) with NBS-Hg(OAc) 2 -R'OH (A), dibromantin-Hg(OAc) 2 -R'OH (B), NBS-AgOAc-R'OH (C), or dibromantin-AgOAc-R'OH (D) in DMF under argon provides corresponding carbamates ( - ) in nearly quantitative yields. ... Treatment of a series of carboxamides with A, B, C, or D in DMF provides the corresponding carbamates in nearly quantitative yields.
